The cooldown day dragged like molasses, Richard's own body feeling both familiar and confining after the sensual freedoms of Sophia's form. He paced the family home, mind replaying the week's indulgences—the strap-on thrusts from Laura, the scissoring climaxes that left them drenched and breathless. But restraint gnawed at him; no swaps meant no escapes into other skins, no fresh waves of arousal from unfamiliar curves. By evening, he crashed early, body heavy with unmet tension, dreams swirling with fragmented touches and moans.
Midnight struck with the system's chime, a vibration rippling through his core. Text flickered in his vision: Swap initiated. Target: Cousin Emily. Duration: Seven days. Cooldown: One day. Adapt and immerse.
Consciousness yanked away, depositing him in a bed that wasn't his. Soft sheets cradled a heavier frame, belly protruding in a gentle swell under a loose nightgown. Richard's eyes snapped open, hands instinctively roaming downward. Fingers splayed over the rounded abdomen, feeling the taut skin stretched over the seven-month pregnancy, a subtle kick fluttering beneath his palm. Higher up, breasts weighed full and tender, nipples already beading with moisture against the fabric.
He sat up slowly, the shift sending a sway to his chest, milk leaking in tiny droplets that soaked the gown. Emily's body—his now—hummed with hormones, pussy throbbing faintly with the constant undercurrent of need that pregnancy amplified. He peeled off the nightgown, standing before the full-length mirror in the dimly lit bedroom. The reflection showed a woman in her mid-twenties, curves amplified by the bump: hips widened for birth, thighs plush, dark hair tousled from sleep. Breasts hung heavy, veins tracing blue paths under pale skin, areolas darkened and puffy.
Curiosity overrode caution. Richard cupped one breast, thumb brushing the nipple, and a warm spurt of milk arced out, splattering the mirror. The sensation jolted him—tingles shooting from the tip straight to his clit, pussy clenching in response. He squeezed again, harder, watching twin streams jet forth, the relief mingled with building heat. Milk dribbled down his belly, pooling in the navel, the scent sweet and earthy filling the air.
Emboldened, he lay back on the bed, knees falling open. One hand kneaded the free breast, coaxing more lactation that trickled over fingers, while the other trailed south. Pubic hair curled damply above swollen labia, the pregnancy making everything hypersensitive. Middle finger parted the folds, finding the entrance slick—not just from arousal, but the creamy discharge common in late gestation. He circled the clit, swollen and eager, then pushed two fingers inside, the walls gripping tight around the intrusion.
The fullness echoed the baby's presence, but the strokes built a different pressure. He pumped steadily, thumb flicking the nub, milk still leaking from the breast he pinched. Hips rocked up, belly rising and falling, breaths quickening as pleasure coiled low. A third finger stretched him further, curling to rub the front wall, and the orgasm crashed sudden and fierce—pussy spasming, juices squirting around his hand, a low groan escaping Emily's lips. Milk sprayed in rhythm with the contractions, soaking sheets and skin.
Panting, he withdrew, licking the tangy mix from his fingers, the act strangely intimate. The door creaked then, and Alex—Emily's husband, a broad-shouldered man in his late twenties with tousled brown hair—entered, rubbing sleep from his eyes. 'Em? Heard noises... you okay?'
Richard froze, then nodded, pulling the sheet up modestly. 'Just... restless. The baby's kicking.' Alex's face softened, crossing to sit on the bed's edge, hand resting on the bump. His touch was gentle, thumb stroking the curve, but Richard felt the spark—Emily's body responding with a fresh gush between legs.
'Want me to help?' Alex murmured, leaning in to kiss the forehead, then trailing to lips. The kiss deepened naturally, tongues sliding together, his hand migrating to a breast. When his palm pressed, milk welled, dampening his shirt. He pulled back, eyes widening, then grinned. 'Already? Let me take care of that.'
Without waiting, he shrugged off his tee, mouth descending to latch onto the nipple. Suction pulled strong, milk flowing into his mouth as he suckled, tongue swirling the areola. Richard gasped, hand cradling his head, the dual sensations—relief from engorged tits and arousal spiking in his core—overwhelming. Alex switched sides, drinking deeply, free hand dipping under the sheet to cup the mound, fingers probing the wet slit.
'God, you're soaked,' he growled against skin, inserting a finger alongside Richard's earlier efforts. The stretch burned sweet, prostate-equivalent spot in this form yielding to his thrusts. Richard bucked, milk dribbling from the unattended breast, pussy fluttering around the digit. Alex added another, scissoring to open him up, thumb grinding the clit until stars burst behind eyelids.
He released the nipple with a pop, lips shiny with milk, and stripped his boxers. Cock sprang free, thick and veined, pre-cum beading at the tip. 'Need you inside,' Richard whispered, Emily's voice breathy, legs spreading wider around the belly. Alex positioned carefully, rubbing the head along the folds, coating himself in juices before pressing in.
The penetration filled him utterly, walls stretching around the girth, the angle hitting deep with each inch. Richard moaned, hands on Alex's shoulders, urging him on. He thrust slow at first, mindful of the pregnancy, hips rolling to grind the base against the clit. Milk leaked freely now, smearing between their chests as bodies slapped together.
Faster now, Alex's breaths ragged, one hand bracing the bump while the other tweaked a nipple, eliciting more sprays. 'Fuck, Em, so tight... milking me already.' Richard clenched deliberately, drawing a curse from him, the coil tightening unbearably. Climax hit first for Richard—pussy clamping down, squirting around the pistoning cock, cries muffled against Alex's neck. He followed seconds later, pulling out to cum in ropes across the belly, the warmth mixing with milk trails.
They collapsed side by side, Alex's arm over the swell, fingers idly circling a nipple to coax residual drops. 'That was intense,' he said softly, kissing the shoulder. Richard hummed agreement, body humming with aftershocks, the system's secret safe for now. Six more days loomed, filled with this new role—nurturing wife, swollen with life, sharing bed and body with a man who craved every inch.
Morning light brought routine: Alex helping with a shower, soapy hands lathering the breasts until milk foamed under the water, his fingers slipping back inside for a quick finger-fuck against the tile. Breakfast followed—pancakes at the kitchen table, Richard's feet propped up, Alex feeding bites while his hand rested possessively on thigh, inching higher to tease the still-sensitive folds.
The day unfolded in domestic rhythm laced with erotic undercurrents. A prenatal check-up where Richard endured the doctor's probing, the stirrups exposing him vulnerably, arousal flickering despite the clinical setting. Back home, Alex bent him over the couch for a lazy afternoon fuck—entering from behind, one hand on the belly, the other rubbing circles over the clit until they both shuddered to release, cum dripping down thighs.
Evening wound down with dinner, then bed, where Alex suckled again before sliding in missionary-style, careful thrusts building to a shared peak. As sleep claimed them, Richard's mind raced with the novelty—the weight of pregnancy, the constant lactation, the raw physicality of coupling in this form. The week promised deeper dives into Emily's world, bodies entwining night after night, the swap weaving him tighter into forbidden familial threads.
